Significance of Crossing Over

Crossing over is of great significance.
1. Linear arrangement of genes: Crossing over clearly illustrates the linear arrangement of genes in the chromosomes.

2. Chromososme Maps: The frequency of crossing over is very useful to construct the chromosome maps.

3. Recombination: Crossing over produces new combination of genes.

4. Variations: Crossing over leads to genetic variation which is the raw material for evolution.
